This is a short video on how to make your fog lights come on with your high beams. Below is the link to the forum that I used to do this. Scroll down a bit and he has pictures and a description. www.gm-trucks.c...
+Jacob Bennett is there a mod to make the fog lights come on every time the headlights come on without having to press the button? I have a 2016 Sierra.
Sold the truck 3 years ago but have a friend that I did this for and his still works. Only problem was the diode had worked its way out a little and needed to be reseated.
My fog lights on my 2015 stopped working relay is clicking & fog light in the cluster turns green when I push the button but there’s no power going to the fuse is there another relay hidden ?
Awesome! Maybe someone can help me with other light issue. 2016 Sierra Denali My “C” lights are dimming after dark or when low beams are on. Is there anything I can do to make them stay bright all the time? It also happens when I switch from Drive to Park Thanks
